This shelf cloud from a good sized mesocyclone moving through May 2020. I’m happy to say I only had one small formerly nice calf shed cartwheeled over a fence. As well as two empty standing gasoline tanks/stands blown over from this one. They have been standing for decades. Any hail missed us. I was however, pelted by horizontal rocks and gravel. Carried by the wind gust coming up the hill over the gravel road lower left frame. Looked like a sand storm coming at me.
I’m estimating conservatively it was a 60 mph direct down draft but it was probably 80 mph. My recording wind gauge is currently down waiting for a replacement moment as the winds here wear out the 120 dollar devices every 4 or 5 years. They are actually incoming next week so that will be fixed. I have recorded a 79mph wind on the ranch historically.
I’ve been an observer of weather for some time. The winds usually affiliated with this type of Arcus cloud CAN be pretty severe. I snapped this image along with a few more. Thought the better part of valor was to avoid the worst of it. “Clever Girl” is only 5 months old and has no hail dents yet. I heard golf ball sized hail in this…. didn’t get it. Only .3 inch of rain but we’ll take what we get.
I thought it was pretty nifty this shelf has 3 horizontal rings looping around rotation clearly visible in this capture. The lightning bolt was a rare one in this storm as it really didn’t light up too much. There were some dangerous bolts. When my truck started getting seriously buffeted, I headed for the barn under that big white roof. I left that building’s white roof in the frame for a reason. It is a good scale. That is 1/2 of the roof of a building which is roughly the size of a regulation foot ball field. I’m almost a mile and 200 feet above that building at the click.
Taken 10 days before it posts mid-may 2020. This is how long it takes me to get a “current” photo in to be published. That is if I bring it to the front of the line. I have to admit I have a bias for big Mammatus. (👀). When I say big you have to realize this storm is about 10 miles long. Admittedly this is a tiny storm for this country that occasionally has 100 mile across mesocyclones develop from these smaller storms. The shelf cloud off to the right was awesome in this storm.
This was one of a series of storms moving south to north along a line that evening. They all were just east of me along Parks/Garst Road up here in Wyotana. The little rainbow as you follow the red gravel road as it curves to the right, was a nice touch from the storm. Lightning? Not so much. The big views we have up on the high ridges gives up 50 to 180 mile long vistas to photograph and observe weather occurring from a distance. I followed this and it’s sister storms moving along the frontal boundary moving through our area. I couldn’t have asked for a better view of this barking dog.
As I type this, the wind blew well over 60 mph last night. Rained sideways for 20 minutes. It said .3 inch but this is suspect lol. I was up photographing the storm come up but got back to shelter before that one came through. I have yet to download the images from that event.
Mammatus clouds tend to indicate that there’s a thunderstorm about. Certainly linked with heavy precipitation some where, mammatus are very impressive at times… Particularly when back lit by the sunset (slit) over my shoulder. That precipitation doesn’t always make it down to the surface before evaporating or sublimating. (Virga). Other times it dumps several inches…
The difficulty of getting enough warm air aloft means that a thunderstorm has to be rather strong before it can form huge mammatus. Often read as a harbinger of strong oncoming storms. I find they are usually a sign of one that has just passed. Aviators taught cumulonimbus cloud avoidance live longer. Particularly with Mammatus about. Notoriously, associated with severe weather, mammatus certainly mark turbulance.
While they look impressive, they have very little impact on life at the surface in my travels. . Mammatus are merely the messengers of their bigger, tougher clouds about the area. Having one pass over RIGHT as the sun passed under the cloud deck to the west
As mammatus clouds don’t usually do damage tohumans directly. They can occur around a very hazardous environment however. Scientists really don’t know much about them. While they’re not that uncommon, it’s difficult to get scientific data back about exactly what’s going on under the thunderstorm’s anvil. They certainly reflect a density change between the air below and the cloud itself. Puffy surfaces like that would indicate micro circular flow environment of trought troughs. It’s a 3D thing going on up there. Very complex as I visualize what is ongoing under there.
Meanwhile, their striking appearance and relative rarity make them good targets for conspiracy theorists. Some believe that they’re the result of weather modification programs. As most conspiracy theories, they don’t hold much water…. or maybe there is some “water” up there lolol I consider this one of the best capture of the species of cloud that I have done to date. Next summer is a whole new set of sky shows.
